How to choose the model of cold dryer for air compressor

Many enterprise users do not understand the considerations of air compressor cold dryer when choosing the overall matching of air compressor. Let's analyze how to choose the cold dryer as the matching equipment of air compressor?

The model of the matching cold dryer for air compressor should be considered from four aspects:


On the one hand, design standard


1. Inlet pressure: 7kg/cm2G


2. Inlet temperature: 42°C


3. Ambient temperature; 38°C


4. Pressure dew point; 2°C


On the other hand, determine the actual air volume m3/min


1. Pressure dew point; °C


2. Operating pressure: kg/cm3G


3. Estimated air volume: m3/min


4. Inlet temperature: °C


Third, ambient temperature: °C


Air volume correction formula:


Estimated air volume × KA × KB × KC × KD = actual air volume.


Four aspects, examples:


1. Customer requirements

a. Estimated air volume: 1.2 m3/min

b. Operating pressure: 7 kg/cm3G

c. Inlet temperature: 45°C

d. Ambient temperature: 44°C

e. Pressure dew point: 10°C

2. Correction: (using the correction formula)

1.2×1×1.26×1.29×0.71=1.38 m3/min

Select the processing volume as 2.0 m3/min
